Hi, Results from a performance test run from last night:
http://people.apache.org/~jukka/jackrabbit/report-2011-08-25/report.html Some remarks: * The BigFileReadTest results are pretty fascinating. It looks like the set of ten 100MB test files fits into the OS buffer cache (the test computer has 4GB RAM) and unlike in previous Jackrabbit versions we can now for some reason avoid invalidating that cache. Or was there some other recent DataStore change that I missed? * We have a notable regression in concurrent read and read/write performance. I'll file a blocker issue for that, to be fixed before Jackrabbit 2.3. * Also login performance is down, most likely due to extra access control stuff. We had a similar issue before 2.2 when some cache setup was taking a lot of time. Perhaps something similar is happening again. * Massive performance improvements for SetProperty and UpdateManyChildNodes tests. I'm not sure which of the recent changes is giving this performance boost. * And as expected from JCR-2835, SQL2 descendant search performance is way better than in 2.2 (note that we backported this change to 2.2.1). BR, Jukka Zitting
